Many believe EQ is a "you've got it or you don't" trait like height or eye colour but that view is false. Emotional intelligence is teachable like any other skill and buildable like any other strength. However, it comes with the same limitations and caveats, individuals start from different levels and it takes effort, it requires changing thought patterns and being outside of your comfort zone. 
Below I outline my approach which works consistently. It is simple - but that doesn't mean easy. Like physical fitness, it takes consistent effort over time.
